Your hardest week is now over. You should be real proud of yourselves! It probably IS the hardest thing any of us can do. And one day at a time is just the way to do it. The urges WILL subside - with time. You can't smoke for 35 years (like I did too), and expect them to go away over night. You have to always watch your back with this Demon. For as long as you still want one, you're still vulnerable.
My mantra is - just say NO, no matter what, to the urges. It's kept me smoke free for 2 years 9 months thus far.
Sounds like you've got a great quit partner at home. Congratulations!
